LYMAN M. JONES AND JAMES \VEDLAKE, OF BRANTFORD, CANADA, ASSIGNORS TO A.HARRIS SON d: COMPANY, (LD.,) OF SAME PLACE.

HARVESTER-BINDER.

SPECIFICATION forming part of Letters Patent No. 450,024, dated April'7, 1891.

Application filed February 20. 1890. Serial No. 341,194:- (No model.)

To all whom, it may concern:

Be it known that we, LYMAN MELVIN J one, manufacturer, and JAMESIVEDLAKE, machinist, both of the city of Brantford, in the county ofBrant, in the Province of Ontario, Canada, have jointly invented acertain new and useful Improvement in Harvester-Binders, of which thefollowing is a specification.

The object of the invention is to arrange 1 o the elevator of theharvester-binder in such a manner that it will freely elevate grainlonger than the width of its canvas, also act so lightly on the heads ofthe shorter grain that all danger of thrashing the grain is avoided, andaccommodate itself to elevate continuously heavy or light grain, holdingit with sufficient pressure to prevent it working endwise; and itconsists in the peculiar construction, arrangement, and combinations ofparts hereinafter more particularly described, and then definitelyclaimed.

In the accompanying drawings, Figure l is a perspective view of theelevating-table of a harvester, the upper elevating-frame being arrangedsubstantially in accordance with our invention, the canvas of the saidupper elevating-frame being removed; Fig. 2, an enlarged detail showingthe jointed or flexible connections between the fixed side of the 0frame of the upper elevating-canvas and the movable side thereof.

A represents the upper canvas rollers, suitably journaled on the endpieces 13 C. The spindle of at least one of the rollers A pro- 5 jectsthrough the elevator side piece D, and is provided with a gear orsprocket wheel in order to connect with the driving mechanism of themachine.

\Ve do not claim anything peculiar in the arrangement of our gearing fordriving the rollers A, and therefore we do not exhibit the whole of saidgearing in the drawings. We may mention, however, that the journals,journal-boxes, or their connections must be 5 arranged in the elevatorside piece D to permit the elevator-frame formed by the rollers A andend piece 0 to rock when the rear end of the frame is raised by thepassing of thegrain between the two elevating canvases. We show one modeof making the connection between the parts on an enlarged scale bar C.The spindle a of theroller A is squared 5 5 and works in acorrespondiugly-shaped hole in the hub 9 of a wheel P, which isconnected to and driven bythe gearing of the machine. As the corners ofthe square makes the diameter of the spindle larger measured from cor-6e ner to corner than when measured from side to side, and the hole inthe wheel-hub is of corresponding size, the roller is driven regularlyby the gear as if the connection between the journal and gear wererigid. The hole in which the spindle a is set is larger at each end thanin the middle, to allow of the other end of the roller rising andfalling without binding therein.

It will be observed that we remove the ele- 7o vator side piece, whichin other machines is placed on the rear of the elevator, similar to thefront side piece D shown in the drawings. By this rear side piece beingremoved the heads of any long grain which may be'ele= vated will extendbeyond the upper canvas, and, in fact, may project outside of the ma-Chine.

The rear end of the upper canvas-frame may be left perfectly free, asits weight will generally be found sufficient to cause the canvas to actupon the grain. In the drawings, however, we show the rear of this framecon nected at each end to a bar M (connected to the seat-board E) by abolt F, extending from 8 5 the bar M and passing through a slot made inthe bracket G, which isfastened to the end piece C, as indicated. Bythis arrangement the loose end of the frame of the upper canvas issupported, but at the same time is so held that it may be pushedupwardly to leave sufficient space for the passage of the grain beingelevated. In order to provide additional pressure on top of the grain,we provide a spring-bar H, connected atone end to the bar M,and passedthrough an eyebolt J, fixed to the end piece C.

Te do not confine ourselves to any particular location for either thespring H or the brackets G, as they may be placed in any suitableposition, or, as we have before intimated, they may sometimes bedispensed with altogether. In order to support the rear of theseat-board E so that the said support shall not interfere With thepassage of the grain when longer than the weight of the elevatortable,we provide an iron or steel support K, rigidly bolted at its lower endto the sill L or its equivalent, and extending obliquely from that pointbeyond the end of the machine, Where it extends uprightly to form asupport, as shown in Fig. 1. The said support, after leaving the sill Lor its equivalent, rests upon the extension N of the wheelframe or itsequivalent, and extending 0bliquely, as shown in the drawings, leavessufficient space below it to admit the truck- Wheels commonly employedfor transporting the harvester.

\Vhat We claim as our invention is- 1. A harvester-binder provided witha rigid front side piece D, having bearings for the upper and lowercanvas rollers, said upper canvas rollers being journaled at their outerends in a rear side piece 0, flexibly connected to said front sidepiece, substantially as described.

2. In a harvester-binder having both upper and lower canvas rollersjournaled in a rigid front side piece and the upper rollers journaled ina rear side piece flexibly connected to the front side piece, and apolygonal spindle for one of said upper rollers, in combination with adriving gear-wheel having a hub with a tapering aperture to allow of therear end of said roller rising and falling, substantially as described.

3. A diagonal support K, bolted to the sill L and resting on theextension N of the wheelframe, extending obliquely to a point outside ofthe elevator-frame, where it is turned upwardly to form a support forthe rear of the seat-board E, substantially as hereinbefore specified.
